Many & UIota;& tau; applications rely on the operationalisation of terminologies, such as multilingual semantic search engines. By operationalisation of terminology, we mean a computational representation of the conceptual system as an ontology of knowledge engineering. This conceptual approach of terminology is close to the ISO principles on terminology as defined by the core standards and . The question then is to study what contribution these standards can make to the construction of ontologies for terminological purposes. In other words, are the terminology principles of ISO soluble in the ontology of knowledge engineering? In this article, we will attempt to provide some answers on the feasibility of implementing ISO principles in description logic, the dominant model in knowledge representation. We will illustrate our proposition with Protege, the most popular environment for building ontologies. Facing the issues raised by this approach, the article will end with the ontoterminology building environment Tedi directly linked to the ISO principles.
